I have created a virtual service using RR message pair. Now I want to add few more transactions into this vsi and also update some of the existing transactions. Hence I load the recording session (vrs file) of the previously created vsi and select option button "Merge" from the recorder. However I observe that many times my virtual service doesn't get updated for the new transactions. I have also tried creating a new vsi and combining it with the previous vsi but strangely this too doesn't work. As a workaround i have to manually copy the transactions from one vsi to another. Not sure where exactly I'm going wrong. Has anyone else faced any such issue or has any suggestions to overcome this please?
